it is a cause to think carefully about doer’s qualification level.
lack of worked over project documentation which is required to make an appropriate repair without faults.
The work without a contract-
lack of the responsible person for the work and its result.
Project without specifications (matching of furniture, lamps, decorative materials …)-
necessity of searching all interior components by yourself which leads to inconsistency between pictures from the designer and the results, and to the other difficulties during installing these components.
Project without realization or designers support during the repair-
high probability that the result will be different from the design project, the constant facing with inconsistencies, necessity of the customer’s constant participating during repairs.
